The formation of kidney stones is directly related to personal living environment, diet, heredity, and certain diseases. The main reason for the formation of kidney stones is the concentration of urine and the precipitation of crystalline material inside the urine, which gradually forms by adhering to the mucosa of the renal pelvis. Secondly, the long-term consumption of food containing high oxalic acid, such as strawberries and spinach, increases the oxalic acid content in the body, which also makes it easy to form stones. Patients with hyperuricemia are prone to form uric acid stones, and patients with hyperparathyroid hormone function are also a major factor in the formation of kidney stones. Therefore, the main cause of kidney stone formation is directly related to the concentration of urine, so pay attention to drink more water to dilute urine, urinate regularly and control the diet can effectively prevent stone formation.
